separator for electric accumulators of a basic material and idea.

摘要

A plastic separator particularly suitable for lead accumulators consists of a highly porous base sheet (1), which is joined on its side facing the positive electrode to a network-structured facing or lining surface (2). The facing/lining surface (2) may be drawn from a sheet- like material, similar to an expanded metal. Passages (4) for the escape of charging gases are formed by webs (3) of lesser thickness of the facing/lining surface (2). IMAGE
